Outlook 2003 Attachment Security Warning - can't open attachments

Get "Attachment Security Warning" when trying to open attachments. Only option is to Save to Disk or Cancel.  That's really annoying. These are Word docs, pdf's, etc..

I have done the following but it does not fix the problem.
         Office 2003: Use a registry editing tool to navigate to the following key:
              HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
              Insert a value with the following details:
              Data Type: SZ
              Value Name: Level1Remove
               Value: Semi-colon delimited list of file extensions you wish to allow, e.g.:
               .exe;.dll;.com;.bat;.vbs;.asp;.html;.url;.htm;.asa;.inc;.css;.msi;.cab
               Restart Outlook for the changes to take effect.
I'm sure this key is present and correct for .doc;.xls;.pdf;.ppt

Need further suggestion.  Thanks.

Yje key you changed sets attachment blocking for the specified extensions to "level 2", which is why you still get prompted to save everything.  In a typical configuration this can only be changed by the server administrator, assuming you use Exchange server.

Attachment file types blocked by Outlook

There are two levels of attachment security. Access to Level 1 files is blocked and can't be changed. When you receive an attachment with a Level 2 file type, you will be prompted to save the file to your hard disk. If you use Microsoft Exchange Server, your system administrator can add and remove file types for both levels of e-mail security. If a file type is added to both levels, it will be treated as a Level 1 file type.


Level 2
There are no Level 2 files by default. If you use Microsoft Exchange Server, your system administrator may add and remove Level 2 file types, or allow you to reduce a Level 1 file to Level 2.

For a possible workaround (as administrator) see:

Note you must exclude the file type from both level 1 AND level 2.
